Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): an intelligent control system for the environment of a ring net cage is shown in figures 1 and 2 and comprises a ring net cage 1, a cable well 2 and a well cover 3, wherein the cable well 2 is buried underground, the top part extends out of the ground, notches 14 (shown in figure 3) are arranged on the top walls of two sides of the cable well 2 along the width direction, the notches 14 are communicated with the cable well 2, a plurality of well covers 3 are arranged, and are arranged in sequence along the length direction of the cable well 2, the well cover 3 is arranged on the notches 14 at the two sides, the well cover 3 can be limited and fixed, meanwhile, the well lid 3 can be opened at any time so as to facilitate the installation and maintenance of the cable by workers, and when the well lid 3 is placed on the notch 14, the upper surface of the well cover 3 can be flush with the top wall of the cable well 2, the ring net cage 1 is arranged and fixed on a plurality of well covers 3, and be provided with rain-proof cover 18 at the top of looped netowrk case 1 to whole looped netowrk case 1 and cable shaft 2 hide rain.

If fig. 2 and fig. 3, the upper surface of well lid 3 is located well lid 3 along the fixed reinforcing bar handle 16 that is provided with in length direction's both sides to make things convenient for the staff to carry well lid 3, then the well is gone into and is installed the maintenance to the cable conductor, the heavy groove 17 has been seted up to the upper surface that still is located reinforcing bar handle 16 department simultaneously at well lid 3, reinforcing bar handle 16 can sink into to heavy inslot 17 completely, in order to avoid reinforcing bar handle 16 protrusion in the upper surface of well lid 3, and the fixed influence that causes of installation to ring net case 1. In addition, all be provided with sealing strip 15 at well lid 3 and notch 14 and two adjacent well lid 3's contact site, sealing strip 15 is used for sealing between well lid 3 and notch 14 and two adjacent well lids 3 to reduce the possibility that the rainwater falls into in the cable shaft 2, thereby can effectively reduce the possibility of 2 inside humidity of cable shaft or even ponding, operate with the guarantee cable conductor safety and stability.

As shown in fig. 3, because the cable well 2 is buried underground, the surrounding soil layers can seep water into the cable well 2, so that water is accumulated in the cable well 2, and the waterproof coiled material 13 is laid on the bottom and the wall of the cable well 2, so that the surrounding soil layers can be effectively prevented from seeping water into the cable well 2, the possibility of long-term water accumulation in the cable well 2 can be reduced, and the cable can be further ensured to run safely and stably for a long time.

As shown in fig. 3, when the rain is continuously rained or even rainstorm occurs, the sealing strip 15 and the waterproof roll 13 of the waterproof measure are far from meeting the waterproof requirement of the cable well 2, rainwater and underground water still enter the cable well 2 to cause water accumulation inside the cable well 2, so that the cable is soaked in water for a long time, the insulation performance of the cable is reduced, and aging of the cable is accelerated, in order to solve the problem, a water suction pump 4 can be installed and fixed on the bottom of the cable well 2, a water suction pipe 5 is connected to a water outlet of the water suction pump 4, the water suction pipe 5 extends out of the cable well 2 along the wall of the cable well 2, the water suction pipe 5 is fixed on the wall of the cable well 2 through a plurality of U-shaped hoops 6, a floating ball liquid level meter 7 is installed on the top wall of one side of the cable well 2 along the length direction, a floating ball on the liquid level meter 7 is placed inside the cable well, when the inside ponding of cable shaft 2, the staff can start suction pump 4, takes out cable shaft 2 with ponding through drinking-water pipe 5 to avoid the cable line to soak in aqueous for a long time, and lead to the cable conductor insulating properties to reduce, thereby prolonged the life of cable line, improved the safety in utilization of cable line.

Like figure 3, in addition, the shaft bottom of cable shaft 2 is the rectangle to there are four corners, sunken by three edge angle wherein to the shaft bottom of cable shaft 2, thereby this corner is the minimum in whole cable shaft 2 shaft bottoms, and with the minimum in cable shaft 2 shaft bottoms of suction pump 4 installation fixed in cable shaft, thereby can take out with the inside more ponding of cable shaft 2, with reduce the inside ponding dead angle that appears of cable shaft 2, and can't take out the possibility of cable shaft 2. Meanwhile, after the water pumping pipe 5 extends out of the cable well 2 for a certain distance, the water pumping pipe 5 is bent downwards to one side, so that the opening of the water pumping pipe 5 can be opened downwards, and rainwater is effectively prevented from flowing backwards into the cable well 2 from the water pumping pipe 5; concrete is poured at the contact position of the water pumping pipe 5 and the top wall of the cable well 2, so that the water pumping pipe 5 and the top wall of the cable well 2 are integrated, the contact position of the water pumping pipe 5 and the top wall of the cable well 2 can be sealed, and rainwater can be prevented from permeating.

As shown in fig. 3 and 4, air intake 8 and air outlet 9 have been seted up respectively on cable shaft 2 along length direction's both sides roof, inside air intake 8 and air outlet 9 intercommunication cable shaft 2, install fan 10 on air intake 8, thereby the staff can open fan 10 for a long time, force the air supply to cable shaft 2 inside through air intake 8, wind blows to cable shaft 2 inside, discharge from air outlet 9 again, ventilate to cable shaft 2 inside with the circulation, can be to the inside drying that lasts of cable shaft 2, thereby effectively reduced cable shaft 2 inside long-term possibility that is in the humid state, the operation of giving the cable conductor provides safe and stable environment. In addition, all be fixed the intercommunication on air intake 8 and air outlet 9 and have tuber pipe 11, after tuber pipe 11 upwards extends a section distance, it is downward to a lateral bending to the opening of tuber pipe 11 is down, can prevent that the rainwater from falling into in the tuber pipe 11, through the tuber pipe 11 that sets up, can effectively avoid the rainwater from air intake 8 and air outlet 9 directly falling into in the cable shaft 2, cause the inside ponding of cable shaft 2.

As shown in fig. 5, gauze 12 is disposed at the openings of the two air pipes 11 for blocking impurities such as fallen leaves and garbage bags, so as to prevent the impurities from blocking the air pipes 11 to cause unsmooth ventilation or entering the cable well 2 to be inconvenient to clean; meanwhile, the gauze 12 can also block mosquitoes to prevent the mosquitoes from entering the cable well 2 to gnaw the cable and damage the cable.

The working process is as follows: keep fan 10 to be in operating condition for a long time, through 8 to the inside forced air supply of cable shaft 2 of air intake, wind blows to 2 insides of cable shaft, discharges from air outlet 9 again, ventilate 2 insides of cable shaft with the circulation, can carry out the drying that lasts to 2 insides of cable shaft, in case moist, when 2 inside pondings of cable shaft are monitored to floater level gauge 7, the staff can start suction pump 4, take out cable shaft 2 with ponding through drinking-water pipe 5, can avoid the cable conductor to soak in aqueous.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
